After looking at what `comp-el-to-eln-filename' does, I observe that: (substring (md5 "c:/emacs/git/emacs/native/lisp/hl-line.el") 0 8) "e67628ec" (substring (md5 "//hl-line.el") 0 8) "8fa29c14" That matches the two middle hashes seen above. It looks like `comp-el-to-eln-filename` fails to match the filename prefix against PATH_DUMPLOADSEARCH. It is using case-sensitive matching, but on Windows filesystems are case-insensitive. AndyM
